Overview

CVE-2011-1549 is a medium-severity vulnerability affecting gentoo logrotate. It was published on March 30, 2011 and has a CVSS 2.0 base score of 6.3 (MEDIUM).

This vulnerability has a CVSS 2.0 base score of 6.3, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

The default configuration of logrotate on Gentoo Linux uses root privileges to process files in directories that permit non-root write access, which allows local users to conduct symlink and hard link attacks by leveraging logrotate's lack of support for untrusted directories, as demonstrated by directories under /var/log/ for packages.

Remediation

Check the references section for vendor advisories and patches from gentoo. Update logrotate to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
